Pillow breathability and elasticity

  The air permeability and elasticity of pillows are mainly for pillows made of soft pillow core materials, because other filling materials such as cassia seeds, silkworm sand, grains, and elastic tubes can ensure that the pillows have good air permeability and will not collapse without elasticity. But soft materials such as vacuum cotton, cotton, sponge, etc. generally have the problems of poor air permeability and poor elasticity. According to medical investigations, the prone position occupies a certain proportion in the sleep process of each person. Pillows with poor breathability will make people sleep difficult to breathe, which will seriously affect people's health and may even cause safety problems. At present, most of the pillow manufacturers on the market have considered this problem, and more porous fibers are used to solve this problem. Good elasticity mainly means that the soft pillow core material can avoid the collapse of the pillow, ensure the comfortable use of the pillow for a long time, and increase the supporting force for the bending of the neck, but the pillow with good elasticity also has the disadvantage of unstable sleeping posture. The best pillows need moderate elasticity and moderate support.

  When sleeping, the head is very important when it is in a reasonable position on the pillow. Generally speaking, it is best to put the head on the center of the pillow, so that it can stabilize the posture of sleep and avoid frequent fall of the posture at night to cause the pillow to fall; The second is to allow the neck to have a certain supporting force and maintain the normal physiological curve of the body. The normal sleeping position is to lie on the head with the head in the middle of the pillow, and the neck is placed on the edge of the pillow. The pillow will play a supporting role on the neck and will not cause Cervical spine pressure. If you use a non-elastic pillow core material, you can squash the pillow in the middle and place the neck high on the pillow so that the cervical spine is neither flexed nor laterally bent. Maintain a proper backward extension so that you do n’t get up in the morning Will cause cervical pain.
